【Sobristic Adventures】Old TV problems will be able to repair the original science basis!

I remember when I was young, I often encountered such a situation: the TV image was blurred, the sound was problematic, and the parents walked over to take a shot.
However, today's flat-panel TVs do not work. Why? In fact, there is a scientific basis for this, Xiao Bian this will give you the secret:

First look at the difference between an old TV and a flat TV:

Old TV motherboard

Smart TV motherboard

From the picture you can draw this conclusion:
The old circuit board is a welding process. After aging, it will inevitably become loose. The unstable display screen is a large picture tube. Through the current magnetic field imaging, the instability after aging is also normal. At this time, it may happen that the interface will be loosened. Docile"

1. When high-voltage power encounters moisture and air pollutants, it will corona discharge, resulting in ozone generation and corrosion of the tube electrode.
2. An abnormal high-voltage pulse can cause arcing and damage the electrode coating, exposing the electrode to ozone and accelerating corrosion.
3. High-temperature and high-pressure oxidation will release the bromide flame retardant of the insulated plastic parts of the socket and induce further discharge. The bromide will generate acidic and salty substances on the tube base due to the electrochemical action, corroding the electrode, and aging. plastic.
4, high-pressure electrostatic dust adsorption, TV does not work without high temperature dust absorption, increase the leakage within half an hour after boot.
In this terrible physics and chemistry trinity, under the all-dimensional three-dimensional combat of temperature and humidity amphibious amphibious, the tube tube seat falls into a vicious circle of increasingly larger contact resistance and smaller insulation resistance, eventually leading to contact + poor insulation phenomenon, the picture tube High voltage leakage, focus is blurred.

The new circuit board using patch technology, the screen is LED, each pixel is a separate LED lights, the overall stability is very strong. The kinescope of a picture tube television is connected to other circuits through a connector such as a header, which is a thing that operates in a complex and harsh environment where high voltage and high temperature oxidize strongly.


to sum up:

Therefore, for an old TV in the home, the touch may be a little better, and the electrode contact will be better, temporarily return to normal work; or because the TV boot temperature will disperse the moisture and reduce the leakage current. Therefore, it is possible to wear out the time and let the leakage current naturally become smaller, resulting in an illusion that the television is effective.

But for the new smart TV, it can no longer use the old method to solve the problem. The internal integration of the smart TV is very high. Indiscriminately tapping not only can not be repaired, but may cause irreparable damage! How to maintain smart TV? Solve the Caton? You can install a sofa butler!

Installation sofa butler application market, first of all to ensure that smart TV applications installed security and clean! The applications installed or uninstalled by the sofa butler will automatically delete the remaining files such as application apk packages, which are safe and secure.


Which in the toolbox section also integrates a practical smart TV a key to optimize acceleration and garbage cleanup capabilities, so that the smart TV at all times to maintain the best state, the principle of Caton and the virus!
